Effect of Sodium Dodecyl Sulfate on Stability of MXene Aqueous Dispersion.

ABSTRACT: MXenes suffer from severe oxidation and progressive degradation in aqueous media due to its poor chemical stability. Herein, sodium dodecyl sulfate (SDS) is employed as an efficient protectant for long-term storage of Ti₃ C₂ T_x -MXene aqueous dispersion. Experimental data support SDS's capability to protect oxidation-prone sites on Ti₃ C₂ T_x nanosheets, providing extended colloidal stability of up to 213 days. Concentration-dependent anti-oxidation effect articulates that 1.5 mg mL^-1 is deemed as an ideal SDS dose for Ti₃ C₂ T_x to achieve optimal oxidation-resistance in aqueous solution. Additionally, a chroma strategy is developed to instantly and precisely measure the oxidation d
